Abstract

We propose a construction of the optoelectronic pattern recognition system with binary power spectrum for target recognition, and apply liquid crystal spatial light modulators to this system. In addition, we utilize the minimum average correlation energy method and multi-level quantized reference function. The constructed reference function could be implemented at the input plane of the liquid crystal spatial light modulator. Numerical result is presented.
